36-Spaceship Earth: Overseeing space…& Earth
When Christa Peters-Lidard cold-called the head of NASA’s hydrology lab as an undergrad, she wasn’t thinking she’d eventually land that very position. Now as the Acting Director for Sciences and Exploration at NASA’s Goddard Space Flight Center, Christa oversees several critical programs – either orbiting, like the James Webb Telescope, or currently in development – by ensuring scientists have the resources they need for a successful mission.

Distillations: Mapping the seafloor with computer games
Many might think that we know most or all there is to know about our world. On the surface, that might be somewhat true. But below the surfaced, we’ve mapped less of the oceans than of places outside our world like Mars and our moon.

Halloween special: Nessie & the kraken
We’ve all heard stories about fantastical creatures that people swear they’ve seen and have evidence of but can never be confirmed. Think Bigfoot or the Loch Ness monster. Mermaids or the Kraken. While there’s no evidence backing the existence of these creatures, either in present day or at any point in the past, there must be a reason why such legends were created in the first place. In most cases, …

Halloween special: Sasquatches & mermaids
We’ve all heard stories about fantastical creatures that people swear they’ve seen and have evidence of but can never be confirmed. Think Bigfoot or the Loch Ness monster. Mermaids or the Kraken. While there’s no evidence backing the existence of these creatures, either in present day or at any point in the past, there must be a reason why such legends were created in the first place. In most cases, the legend in grounded in fact.

Navigating the challenge of COVID and cruises
All of our personal and professional lives were impacted from the very beginning of the COVID-19 pandemic outbreak in early 2020. The schedule of ocean expeditions was hit especially hard, and field-based ocean research continues to work through the ongoing challenges of coronavirus.

22-Storied careers: Ocean sensors and dog scenters
Tommy Dickey is an emeritus oceanographer from U.C. Santa Barbara and Naval Operations Chair in Ocean Sciences. His modeling and observational research yielded ocean monitoring technologies and tools. For retirement, Tommy trains and deploys Great Pyrenees as therapy dogs, while studying scent dogs’ capacity to detect COVID-19.

21-Storied careers: Scouring seas from the skies
This episode is about how satellite technology is being used to study a big chunk of the earth’s surface. Seventy percent of the earth comprises water but we know very little about it. Color sensors aboard some satellites can actually reveal a lot about phytoplankton or microalgae blooms that are linked to ocean temperatures. These tiny organisms contribute to half the photosynthesis on the planet.

16-Ice: Shells of an ice-less past
Brian Huber is a climate detective at the Smithsonian who grew up collecting arrowheads in the woods of Ohio, but now collects and studies fossils from sediment cores. Brian uses fossils of tiny organisms − foraminifera − to track climate over millions of years, including the Cretaceous Hot Greenhouse climate.

12.5-A podcast of ice and fire
Cool off from the summer heat with our next six-part miniseries all about ice – from those who call it home to its use as a tool in science.

6.5-Extinctions: Dinosaurs, volcanoes, the space station, oh my!
Join us for our next six-part miniseries on Extinctions as we learn about the demise of the dinosaurs, what makes a comet “extinct,” the Cambrian and Triassic periods, volcanoes, and the aforementioned (planned) fiery end of the International Space Station!

4-True story: Using TikTok for (shark) science good
Jaida Elcock says she thrives in chaos. And we’re inclined to believe her. From her ridiculously entertaining TikToks on animal facts, to her work with the non-profit Minorities in Shark Sciences (oh, did we mention she’s currently pursuing her Ph.D.), she seems to be managing that chaos pretty well. We talked with her about all of her endeavors, her inspiration from conservationist Jeff Corwin, and what (or who) she would like to see in science.

Knowledge about oceans on other worlds starts with our own
the possibility of finding life in the universe has increased thanks to the ocean analog from our own planet. Samples from Expedition 390, which are collected from aa subsurface environment where basement is in contact with water, will advance our scientific knowledge and may help guide the direction for future astrobiology research as we continue to search for life in Earth’s deep ocean system and on other worlds.

1-True story: Slapped by a (misinformation) shark
David Shiffman is a shark guy. It’s in his Twitter handle, he’s writing a book about it, and he was wearing a shark shirt the day we interviewed him. But more broadly he’s a marine conservation biologist, meaning he studies all sorts of ocean-going animals.

True (science) stories you’ve never heard before
Third Pod from the Sun is back, and we’re going weekly! Join us as we combat misconceptions about sharks, learn how to lasso lizards, hear from a Martian here on Earth, spark science joy via Tiktok, journey to Antarctica, and fight over food with some capuchins!

Staff Picks: Chasing Narwhals
University of Washington biologist Kristin Laidre travels to the Arctic to study animals many of us have only seen in pictures. She has successfully tracked down the elusive narwhal and been up close and personal with a polar bear seeking to understand how the loss of sea ice and the effects of climate change are altering Arctic ecosystems.

Scientists Mine 16th Century Ship Logs for Geophysical Research
As ships explored the world from the Age of Sail through 20th century, mariners kept detailed navigation records using the Sun and stars. Scientists scoured these ship logs, many of which are preserved in European libraries, for clues about Earth’s magnetic field. The work, published in 2000, created the first-ever magnetic field map for the past 4 centuries.

Bowhead whales: A recent success story
Bowhead whales are true northern creatures, swimming only in cold oceans off Alaska, Canada, Greenland, Svalbard and Russia. These bus-size whales have the largest mouths in the animal kingdom, can live for 200 years and can go without eating for more than a year due to their remarkable fat reserves. Bowheads are also a rare wildlife rebound story, with the population north and west of Alaska now numbering more than 16,000. That’s up from the 1,000 or so animals Yankee whalers left behind in bloody waters at the turn of the last century.
